Description

Technical Field

[0001] This utility model is a vibrating sieve device for glass fiber powder, belonging to the field of glass fiber powder production technology. Background Technology

[0002] Glass fiber powder is made by cutting, grinding and sieving specially drawn continuous glass fiber filaments. As a filler and reinforcing material, it is widely used in various thermosetting and thermoplastic resins. Glass fiber powder is used as a filler to improve the hardness and compressive strength of products, and reduce the shrinkage rate, scratch width, wear and production cost of products.

[0003] According to Chinese Patent CN202323070171.5, a continuous vibrating screening device for glass fiber powder production is disclosed. This application includes a casing containing a vibrating motor. A support mechanism is installed at the top of the casing, and the vibrating motor is connected to the bottom of the support mechanism. A lower screen frame, a middle screen frame, and an upper screen frame are evenly distributed on the support mechanism. A quantitative feeding structure enables the quantitative feeding of the glass fiber powder to be screened, achieving continuous and uniform feeding and preventing material accumulation during the feeding process from affecting the screening process. A sealed collection structure is also used to achieve sealed collection of the glass fiber powder during discharge, preventing dust pollution. Existing vibrating screening devices for glass fiber powder require the glass fiber powder to be screened to be poured from the top hopper into the feed box during feeding. This pouring process generates a large amount of dust that floats into the surrounding environment, posing a health risk to personnel if inhaled, thus posing a low safety concern.

[0018] See Figure 2 , Figure 3 and Figure 4The height adjustment assembly includes symmetrically arranged mounting frames 10 at the top of the vibrating screening box 1 and on both sides of the storage box 2. Each mounting frame 10 contains a vertically arranged lead screw 11. A movable frame 12 is fitted onto the outer wall of the lead screw 11, and one side of the movable frame 12 extends out of the mounting frame 10 and connects to the storage box 2. The lead screw 11 is connected to the mounting frame 10 via a bearing, and its top end extends out of the mounting frame 10 and connects to the drive end of a servo motor 13. The movable frame 12 has a threaded hole matching the lead screw 11. The automatic feeding assembly includes several feed inlets 14 arranged in a circular array on the outer wall of the feed cylinder 4. A vertically arranged conveyor shaft 15 is provided in the feed cylinder 4, and a spiral conveyor blade 16 is fixedly fitted onto the outer wall of the conveyor shaft 15. The top end of the conveyor shaft 15 extends out of the feed cylinder 4 and connects to the drive end of a conveyor motor 17. The bottom of the feed cylinder 4 has a conical structure. First, the bucket containing glass fiber powder is moved to both sides of the vibrating screen box 1. Then, the servo motor 13 is started to drive the lead screw 11 to rotate. The lead screw 11 drives the moving frame 12 to move downward. The moving frame 12 drives the storage box 2 to move downward. The storage box 2 drives the feeding cylinder 4 to move downward through the fixed seat 6 until the bottom of the feeding cylinder 4 is inserted into the glass fiber powder in the bucket. The glass fiber powder will enter the feeding cylinder 4 through the feeding port 14. Then, the conveying motor 17 is started to drive the conveying shaft 15 to rotate. The conveying shaft 15 drives the spiral conveying blade 16 to rotate. The spiral conveying blade 16 conveys the glass fiber powder upward through the conveying pipe 7 to the storage box 2. By setting the height adjustment component, the feeding cylinder and the automatic feeding component, the glass fiber powder can be conveyed from the bottom, eliminating the need to pour the glass fiber powder into the storage box from the top.

When feeding material into the vibrating screen box 1, the servo motor 21 is started to rotate. The servo motor 21 drives the feeding roller 19 to rotate. The quantitative feeding trough 20 on the outer wall of the feeding roller 19 is quantitatively loaded with material. When the feeding roller 19 drives the quantitative feeding trough 20 to rotate to the point where the opening faces downward, the glass fiber powder will fall from the quantitative feeding trough 20 into the corrugated telescopic tube 3, and finally into the vibrating screen box 1 for screening. By setting the quantitative feeding component, the glass fiber powder in the storage box can be quantitatively fed into the vibrating screen box, avoiding excessive feeding at one time and affecting the screening effect of the vibrating screen box.

[0020] In operation, first, move the bucket containing glass fiber powder to both sides of the vibrating screen box 1. Then, start the servo motor 13 to drive the lead screw 11 to rotate. The lead screw 11 drives the moving frame 12 to move downwards, which in turn drives the storage box 2 to move downwards. The storage box 2, through the fixed seat 6, drives the feeding cylinder 4 to move downwards until the bottom of the feeding cylinder 4 is inserted into the glass fiber powder in the bucket. The glass fiber powder will enter the feeding cylinder 4 through the feed inlet 14. Then, start the conveyor motor 17 to drive the conveyor shaft 15 to rotate. The conveyor shaft 15 drives the spiral conveyor blade 16 to rotate, which conveys the glass fiber powder upwards through the conveyor pipe 7 to the storage box 2. By setting up a height adjustment component, a feeding cylinder, and an automatic feeding component, the glass fiber powder can be... The powder is conveyed from the bottom, eliminating the need to pour the glass fiber powder into the storage box from the top. This avoids generating a large amount of dust during the pouring process and further improves safety. When feeding into the vibrating screen box 1, the servo motor 21 is started to rotate, which drives the feeding roller 19 to rotate. The quantitative feeding trough 20 on the outer wall of the feeding roller 19 is quantitatively loaded.

By setting the quantitative feeding component, the glass fiber powder in the storage box can be quantitatively fed into the vibrating screen box, avoiding excessive feeding at one time and affecting the screening effect of the vibrating screen box.
